Abstract
An amplifier is provided that includes an output portion that sources and sinks current associated with an output load and an amplification portion that is biased by a relatively small bias current with respect to an output current of the amplifier. The amplification portion provides an amplified output signal to the output portion. The amplifier further comprises at least one impedance component coupled between the output portion and the amplification portion to alter at least one pole associated with the amplifier to mitigate instability of the amplifier related to the relatively small bias current.
